Interfering trajectories in a ballistic Andreev cavity
Pankaj Mandal, Marcel Kaschper, Fernando Dominguez +9
The conventional description of transport through the interface between a normal conductor and a superconductor reduces the system to a one-dimensional problem treating Andreev ref…
Period-doubling in the phase dynamics of a shunted HgTe quantum well Josephson junction
Wei Liu, Stanislau U. Piatrusha, Xianhu Liang +7
The fractional AC Josephson effect is a discerning property of topological superconductivity in hybrid Josephson junctions. Recent experimental observations of missing odd Shapiro…
Balanced Quantum Hall Resistor
Kajetan M. Fijalkowski, Nan Liu, Martin Klement +4
The quantum anomalous Hall effect in magnetic topological insulators has been recognized as a promising platform for applications in quantum metrology. The primary reason for this…
Phase-sensitive SQUIDs based on the 3D topological insulator HgTe
Luis Maier, Erwann Bocquillon, Manuel Grimm +6
Three-dimensional topological insulators represent a new class of materials in which transport is governed by Dirac surface states while the bulk remains insulating. Due to helical…
Very large magnetoresistance in lateral ferromagnetic (Ga,Mn)As wires with nanoconstrictions
C. Ruester, T. Borzenko, C. Gould +7
We have fabricated (Ga,Mn)As nanostructures in which domain walls can be pinned by sub-10 nm constrictions. Controlled by shape anisotropy, we can switch the regions on either side…
Large magnetoresistance effect due to spin-injection into a non-magnetic semiconductor
G. Schmidt, G. Richter, P. Grabs +3
A novel magnetoresistance effect, due to the injection of a spin-polarized electron current from a dilute magnetic into a non-magnetic semiconductor, is presented. The effect resul…
